Redding won five games for Astros last season
Redding, 27, was 5-7 with a 5.72 ERA in 27 games for the Astros last season, including 17 starts and a demotion to the bullpen in July. The right-hander also went 1-3 with a 6.04 ERA at Triple-A New Orleans.
Redding was 21-28 with a 4.75 ERA in four seasons with Houston. He went 10-14 with a team-leading 3.68 ERA in the Astros' rotation in 2003.
Earlier this spring, the Astros released Pete Munro, who started Game 6 of the NLCS against St. Louis last October. Redding, Munro, Carlos Hernandez, Dave Burba and top prospect Ezequiel Astacio were in competition to become Houston's fifth starter.
In February, the Astros avoided salary arbitration hearings by agreeing to a one-year deal with Redding worth $750,000 and a one-year contract with Munro for $700,000.
Quintero, 25, hit .250 with two home runs and 10 RBI in 23 games for the Padres last year. At Triple-A Portland, he hit .317 with five homers and 30 RBI.
